The disgraced former FIFA vice-president resigned from football last June after being charged by the governing body with bribery in connection with payments made to Caribbean football officials.
The director of public prosecutions has decided against pursuing criminal charges against Warner, who is the country's deputy prime minister, in connection with the payments.
The Trinidad Express has published a letter from the Police Service Commission to the country's opposition leader Keith Rowley which says: "On the advice of the Director of Public Prosecutions, no further [action] can be taken in this matter."
Warner said the allegations were "a deliberate campaign designed to demonise me by those who were opposed to me".
Warner has also denied that a centre of excellence and hotel in Trinidad built with almost £20million of FIFA aid money was owned by him.
Lawyers working on behalf on the CONCACAF federation said the centre was owned by two companies belonging to Warner's family, and that he had also arranged for a mortgage to be taken out on the centre.
Warner told local media: "I don't own it, so what is all the fuss about?
"For over one year [FIFA president Sepp] Blatter and his minions are trying their utmost to destroy me and I would not in any way be remotely perturbed by the foolishness taking place in FIFA.
"Blatter believes that he is a god and no one should oppose him at anytime and once you oppose him you pay the ultimate price. I will be the exception and I wish to advise him and his cohorts that in no way he can tarnish my image."
The Trinidad website wired868.com has published documents however linking Warner to the centre, including for a US dollars 11million mortgage taken out in 2007 by two companies, Renraw and CCAM which are both owned by the Warner family - Renraw is 'Warner' spelled backwards.
